[TriEmbed] 2.0mm pitch female connectors

[Glen Smith]

I own a pair of the Pololu ratcheting crimp tool that Pete linked to.
They are marked:
Made in China
SN-28B
For uninsulated receptacles
wide terminals (0.1-1mm^2) AWG 28-18

I've used them on Molex connector terminals, Servo terminals and I'm pretty
sure they will work on DB connector crimp on terminals. Anyone who would
like to try them out or compare them with another brand, let me know. I
usually have them in my tool box (in my truck) at meetings.
